Germplasm Phenotype:

• CS16561  — Arrest and differentiation of axillary meristems, altered leaf morphology, abnormal phyllotaxis, reduced elongation of the primary root.
• CS66951  — No visible phenotype.
• CS67135  — Incompletely penetrant phenotype of reduced apical dominance.
• CS67136  — Abnormal shoot phenotypes similar to Atham1,2,3 mutants but generally more prone to arrest of the inflorescence meristem prior to generation of functional flowers.
• CS67756  — Abnormal shoot phenotype, stems are broader and flatter than in the wild type (mild fasciation); narrow and elongated leaves; fully expanded rosette leaves exhibit less pronounced laminar growth, and more pronounced leaf serrations; delayed transition from vegetative to reproductive development, delayed inflorescence development; inflorescences exhibit aberrant phyllotaxis; cauline leaves typically exhibit epinastic curling, indicative of greater adaxial leaf surface area relative to abaxial leaf surface area. Light and temperature dependent phenotype, phenotype is visible at 16 hours light and 20C or lower.
